Memphis police are investigating after two people were hurt — one of them critically — in a shooting Sunday near the Beale Street Landing.

MPD Lt. Col. Mike Jones said at the scene, near Tom Lee Park, that officers from the North Main Station were working a vehicle accident nearby when they heard shots.

"They heard several shots ring out, so they relocated down here and found two victims shot," Jones said.

The identities of the victims have not been released, but one was male and the other female. Both were transported to the Regional Medical Center at Memphis, the woman in critical condition and the man in noncritical.

One suspect has been detained, according to Lt. Karen Rudolph of MPD.

"Right now, we're trying to figure out the motive behind the shooting," Jones said. "We don't know if the male was defending himself or what. We do know there was another shooter, but we don't have any other information."

Jones said the area was secure as of 8:30 p.m. as crime scene officers worked the area. He said the weapon of one of the victims has been secured but would not say if police were seeking a second weapon.

Police blocked off a section of Riverside Drive from Beale Street to the Beale Street Landing area. Jones said traffic on Riverside, heavily traveled on Sunday nights, would be allowed to resume as soon as investigators finished working the scene.
